Answer:
14
Explanation:
there are 14 electrons in the shells
<span>The answer is A. Gases are spread throughout the air and not packed tightly together. therefore the molecules move quickly and are least densely packaged. They have the highest energy because they also have the highest molecular motion. </span>
If you use rate laws then your answer will be more supported. Laws can not change, so if you use rate laws then the student will get a more accurate answer then if they don’t use rate laws.
Answer:
149.79
Explanation:
Formula
Joules = m * c * delta (t)
Givens
J = 28242
m = ?
c = 4.19
Δt = 63 - 18 = 45
Solution
28242 = m * 4.19 * 45
28242 = m * 188.55
m = 28242 / 188.55
m = 149.79
Answer:
Okay, I think I may actually have an answer for you. I would go with C, "The number of particles able to undergo a chemical reaction is less than the number that is not able to."
Explanation:
I just took a quiz with a similar question, and B is the only gas particle that is able to react. This cancels out all the other answers, as A and B are obviously incorrect based on that information, and it rules out D because T1 is the only sample with a particle able to react. I hope this helps!
